The SKY78187-11 FEM is optimized for LTE Advanced, where Carrier Aggregation is utilized for higher data rates. The combined filtering, RF matching, and TRx switching internal to the FEM optimizes performance for popular Downlink (DL) CA band combinations, all in a compact and low cost solution. The FEM contains all necessary components between the antenna and RFIC transceiver and are optimized to provide superior Rx sensitivity and Tx efficiency.

For the Uplink, the PA blocks support very wide bandwidth operation by intra-band CA up to 40 MHz (200RB) for Bands 1, 2, 3, 7, 38, 40 and 41, and up to 60 MHz (300RB) for Bands 40 and 41. The FEM also supports Downlink/Uplink CA.
